SURGICAL INSTRUMENT.

Application filed January 20, 1927. Serial No. 162,376.

The invention relates to a surgical instrument, and more especially to the class of antrum openers and cleaners.

The primary object oi the invention is the provision of an instrument ot-this character, wherein the tool such as a drill is supported and removably mounted in a holder or adaptor, so that the instrument can be fed through the nostrils ot a patient to operate upon the infected antrum :tor cuttiri away diseased bone or other hard substances and thereafter the tool or drill removed, so that the antrmn can be conveniently and easily cleaned.

Another object of the invention is the provision of an instrument of this character, wherein the adaptor or holder for the tool, such as a drill, is of novel form, whereby the tool or drill can he brought into proper position for operation upon the infected antrum of a patient, without liability 01' in jury to the nostrils of such patient, when in the act of inserting the instrument or its removal therefrom and after operation upon the bone or other hard substances in the region ot the antrum, the latter can be readily and conveniently cleaned by washing out such parts.

it further object of the invention is the provision of an instrument oiii this character, wherein a drain can be attached or the instrument when inserted in the nostril oi? a patient can be held in proper position for operation upon the patient, the instrument being of novel form to eliminate the possibility of the insertion thereo't too far or in any manner injuring the tissues of the nostrils.

A still further object of the invention is the provision of an instrument of this character, which is extremely simple in con struction, thoroughly reliable and eiiicient in its purpose, strong, durable, and inexpensive to manufacture.

lVith these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts, as will be hereinatter more fully described in detail, illustrated in the accompanying drawing, showing the preferred embodiment of the invention, and pointed out in the claims hereunto appended.

In the accompanying drawing li igure l. is a side elevation of the instru ment constructed in accordance with the invention.

Figure 2 is a :l'ragmentary vertical longitm dinal sectional view through the instrument.

Figure 3 is a sectional view on the line 3-3 oi? Figure 1 looking in the direction of the arrow.

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail the instrument comprises a curved tube 5, which is oi the required length and size in cross section, preferably made from metal, although the same may be made from any other suitable material having a rounded or beveled end 6, while the opposite end of said tube 5 emerges into an enlarged barrel preferably straight and of the required length having formed therewith a shank S carrying a handle 9, the latter being made detachably fast to the shank in any suitable manner. This handle 9 by reason of the form of the shank S is disposed at an angle to the barrel 7 of the instrument and said handle is of the required length and external configuration to meet the fancy oi? the user oi. the instrim'ient.

Removahly fitted in the tube and barrel 5 and 'i' is a drill comprising a lip 1.0 which is projected through the free end ot the tube and this tip 10 is connected with a flexible stem 11 which is coextensive with the length of the tube 5 and is adapted to conilornfto the conformation thereof, the stem 11 being joined with-an anle 12 which fits within the barrel 7, the said axle 12 being formed with a reduced shank 13 for detachable engagement in a socket or chuck l-(l: carried on the outer end ot a flexible driving shaft 15 of any approved type. This driving shaft 15 operated from any suitable source of power.

The drill including the tip 10, stem l1. and axle 12 slidably held within the tube 5 and barrel 7 of, the instrument and can be readily removed therefrom, whereby said drill can be extracted after use. i

The l'arrel 7 has tormed thereon a cross head 16 having eye terminals 17 and said head 16 is formed with the barrel at an intermediate point thereof and constitutes a stop to limit the insertion of the tube within the nostrils of a patient and in addition will permit the attachment of a receptacle thereto in any suitable manner so that when the drill 5 has been removed from the tube 5 and its barrel 7 the instrument will serve as a drain and also as a nozzle for washing out the infected part. The instrument is used primarily for opening antrums and also for washing; out the infected antriun either before or after the drilling operation.

YVhen the instrument is to be used as aiozzle for washing out infected parts, the c removed from the instrument and attached to the barrel 7 is arubber tube (not shown) so that water or other liquid can be introdiiiced through the barrel 7 and tube and discharged from the end 6 of the latter directly onto the infected parts.

5 is first inserted into the nostril of the patient and is held in proper position for operation on the antrum by means of the handie 9. Thereafter the drill is inserted through the barrel 7 into the tube 5 so that the drill tip 10 will be disposed beyond. the end 6 of the tube 5, whereupon the shank i3 is engaged in the chuck 1 on the flexible power shaft and motion from the latter is transmitted to the tip 10 which will cut through bone or other hard substances for the opening of the antrum. lVhen thisoperation has been completed the drill is remz'wed from the tube 5 and its barrel 7 so that the part operated upon can be drained. Should it be desired to wash out the infected part a rubber tubeis attached to the barrel 7 and Water or other liquid can be introduced through said barrel 7 and tube 5 for discharge from the latter onto the infected part, the handle 9, being detached at this time. In this manner a sterile water or antiseptic solution can be forced through the instrument into, the antrum to wash it so as to wash the antrum in an easy and almost painless manner.

in the operation of the instrument the tube If found desirable after the insertion of the tube 5 in the nostril of the patient a band or strap can be attached to the cross head 16 such band to encircle thehead so as to retain theinstrument in position without reipiiring the operator to hold such instrument by thehandle 9 thereof until the period of drilling. operation.

From the foregoing it is thought that the construction and manner of use of the instrument will be clearly understood and therefore more extended explanation has been omitted.

hat is claimed is: V

'l. in an antrum drill and cleaner, a curved tube having an enlarged barrel at one end and opened at its opposite end, a handle connected with said barrel, and a drilling element removably insertable throughthe bar rel and into the tube to have its drillingtip exposed through the open end of said tube.

2. In an antrnmdrill and cleaner, a curved tube having an enlarged barrel at one end and opened at its opposite end, a handle coni'iected with said barrel, a drilling element rcmovably inse-rtable through the barrel and into the tube to have its drilling tip, exposed. through the pen end of said tube and a cross head on the barrel intermediate the ends thereof and having eye terminals.

3. In an anti-uni drill and cleaner, a curved tube having an enlarged barrel at one end and opened at its opposite end, a handle connccted with said barrel, a drilling element reinovably insertable through the barrel and into the tube to have its drilling tip exposed through the open end of said tube and a cross head on the barrel intermediate the ends thereof and having eye terminals, the handle b ein disposed angularly with respect to the axis of the barrel.

In testimony whereof, I ailix my signature hereto.
